ABSTRACT:
A method of recovering a target data object. In one embodiment, the method includes restoring the target data object to a data state that existed at a point of time prior. Once the target data object is restored, a first object is retrieved from backup memory, wherein the first object comprises a plurality of transactions for modifying the target data object. After the target data object is restored, the target data object is modified in accordance with the transactions of the first object. A second object is retrieved from backup memory, wherein the second object comprises a plurality of transactions for modifying the target data object. The second object is retrieved from backup memory before the target data object is modified in accordance with all of the transactions of the first object.
